This test is usually used to simulate the free fall of the product during handling and to examine the product's ability to resist accidental impact. Generally, the drop height is based on the weight of the product and the probability of falling. The drop surface should be a smooth, hard, rigid surface made of concrete or steel (if there are special requirements, it should be determined by product specifications or customer test specifications).
For different international standards, even if the products are under the same weight, the drop height is not the same. For handheld products (such as mobile phones, MP3, etc.), most drop heights are between 100cm and 150cm, and IEC is for ≦2kg. The product recommendation should meet the drop height of 100cm and can not be damaged. The recommended drop height is 122cm for MIL. Intel recommends a drop height of 150cm for handheld products (such as mobile phones). The severity of the test depends on the height of the drop, the number of drops, and the direction of the drop.
Free fall test purpose
Determine the suitability of the product to be dropped during handling due to rough handling, or to determine the minimum level of safety required for safety. This experiment is mainly used for non-packaged experimental samples, and its packaging can be used as part of the sample in the shipping box.
